If you do not experience the flickering on any other device, it could be a setting on the graphics of your computer. I will post a link below that provides more information. Hope this helps!

have a Slingbox M2 connected with component input to the M2.
Using iPad or old notbook (win 10 client) the picture is fine.
Using a 6 month old ASUS notebook win 10 64 bit os the brightness of the picture varies and looks like a "flicker" or something like an unstable white level in an ancient thick TV, The notbook has two GPU's of which one is embedded int the Intel CPU and the other one is Nvidia Geforce GTX 850M.
Regardless of which GPU is selected the picture flickers.
Any ideas of what may be the problem.
I could also use suggestion to a media player with remote controle making swapping channels easy instead of fiddeling around with the notebook PC.
